A payphone (alternative spelling: pay phone) is typically a coin-operated public telephone, often located in a telephone booth or a privacy hood, with pre-payment by inserting money (usually coins) or by billing a credit or debit card, or a telephone card. Prepaid calling cards also facilitate establishing a call by first calling the provided Toll-free telephone number, entering the card account number and pin, then the desired connection telephone number — also offering the benefit of establishing many telephone number connections during a single payphone session. An equipment usage fee may be charged as additional units, minutes or tariff fee to the collect/third-party, debit, credit, telephone or prepaid calling card when used at payphones.
